  "abstract": "Predicting the distance traveled by landslides, avalanches, or debris flows is of primary interest for risk management and for limiting the devastation of these natural hazards. The increase of the run-out with the volume of the landslide is a crucial feature that has been documented for geophysical flows for decades. Laboratory-scale experiments have also managed to reproduce the dependence in the flow size for the runout for a granular heap sliding on an incline. However, the physical mechanism of such a feature is still debated. Here, we propose a simple model, which combines frictional sliding and granular column collapse, to explain the runout of landslides on an incline. Numerical simulations using depth averaged models support the model quantitatively. The model accurately represents both experimental data and natural field data.",
